34
* This header is effectively a "namespace multiplexor" for the
35
* user level XFS code. It provides all of the necessary stuff
36
* such that we can build some parts of the XFS kernel code in
37
* user space in a controlled fashion, and translates the names
38
* used in the kernel into the names which libxfs is going to
39
* make available to user tools.
41
* It should only ever be #include'd by XFS "kernel" code being
42
* compiled in user space.
44
* Our goals here are to...
45
* o "share" large amounts of complex code between user and
47
* o shield the user tools from changes in the bleeding
48
* edge kernel code, merging source changes when
49
* convenient and not immediately (no symlinks);
50
* o i.e. be able to merge changes to the kernel source back
51
* into the affected user tools in a controlled fashion;
52
* o provide a _minimalist_ life-support system for kernel
53
* code in user land, not the "everything + the kitchen
54
* sink" model which libsim had mutated into;
55
* o allow the kernel code to be completely free of code
56
* specifically there to support the user level build.
65
* Map XFS kernel routine names to libxfs.h names
